My inaugural adventure up Falls Creek on Deepwater-Cotton Hill Rd. was less than stellar, though quite interesting and informative. It seems there is a pretty nice and large waterfall very near the bottom of the run, which I would probably consider worth photographing, if I could get to it. It's about 30'-40' and in a pretty dangerous little gorge and it was also not the best conditions for us, with lots of rain and mud. This is not your family sedan friendly road. The location is further complicated by the amount of garbage dumped here. Too bad.
From the Midland Trail between Glen Ferris and Charlton Heights, turn onto CR 13 and cross Kanawha River on the green bridge. At the end of the bridge, turn left and follow the road up and along the creek. About a quarter mile up there is a 90 degree turn and shortly after that is a tall waterfall. Continuing up this road you will find some other smaller falls and nice creek/water features, however, at about a mile up, the road is washed out at a culvert. I'm told this road is not worth driving any further than the falls at the bottom. (January 2017)
UPDATE: The Deepwater-Cotton Hill Bridge at CR 13 is now closed and it doesn't appear to have a projected reopening, but check with you county engineer to find out more if you want to. The other way to get here is to cross the river downstream at Mongomery and go east on WV 61 for 5.4 miles to a sharp switchback. Continue straight through the switchback onto Boonesboro Rd. (CR 61/29). Follow upstream to the Deepwater-Cotton Hill Bridge at CR 13. About 3.5 miles. This end of the road is where Falls Creek Falls is. Might as well have a look for yourself.
Up the creek you may find a nice shot or two. This road goes (CR 13) will take you over to Beckwith Rd. It's 6.8 miles of unpaved road and I would not recommend you try driving it. I didn't want to go much more than a mile in before I turned around. It's pretty bad.
